Air Suspension

The air suspension system on the 2006 GX470 is something you really need to pay attention to. It's great for ride comfort and adjusting the vehicle's height, but it can become a headache as the car gets older. The main issue is that the air bladders can start to leak. This usually happens because the rubber deteriorates over time, especially if the vehicle has been exposed to extreme temperatures or harsh conditions. When an air bladder leaks, the system has to work harder to maintain the correct ride height. This puts extra strain on the air compressor, which can eventually cause it to fail too. Replacing the air suspension components can be quite expensive. The air bladders themselves aren't cheap, and the labor costs can add up quickly. Some owners choose to replace the entire system with a traditional coil spring suspension. This is a more permanent solution that eliminates the risk of future air suspension problems. However, it will change the ride quality of the vehicle. It's a trade-off between comfort and reliability. If you're considering a GX470 with air suspension, be sure to have it thoroughly inspected. Look for any signs of sagging, unusual noises from the compressor, or error messages on the dashboard. Addressing these issues early can save you a lot of money and hassle in the long run. Regular maintenance, such as cleaning the air suspension components and checking for leaks, can also help extend the life of the system. Overall, while the air suspension offers a luxurious ride, it's one of the most common and potentially costly problems to watch out for on the 2006 Lexus GX470.

Rust

Rust is another potential issue with the 2006 Lexus GX470, especially if the vehicle has spent a lot of time in areas where they salt the roads during winter. Salt accelerates the corrosion process, and it can cause rust to form on the undercarriage, frame, and other metal components. Rust can weaken the structural integrity of the vehicle and lead to costly repairs. In severe cases, it can even make the vehicle unsafe to drive. The best way to prevent rust is to regularly wash the vehicle, especially during the winter months. This will help remove any salt or other corrosive materials that may have accumulated on the undercarriage. You can also apply a rust inhibitor to protect the metal surfaces. When inspecting a used GX470, pay close attention to the undercarriage. Look for any signs of rust, such as flaking paint, bubbling, or corrosion. If you see any rust, have it inspected by a professional to determine the extent of the damage. Minor surface rust can usually be treated with a rust converter, but more severe rust may require welding or other repairs. Prevention is always better than cure when it comes to rust. Taking steps to protect your GX470 from rust will help extend its life and maintain its value.

Leaking Actuator

A leaking actuator is another common problem reported by owners of the 2006 Lexus GX470. The actuator is a component of the braking system that helps to control the flow of brake fluid. Over time, the seals in the actuator can wear out and start to leak. This can lead to a loss of brake fluid, which can compromise the braking performance of the vehicle. If you notice a leak near the brake master cylinder, or if you experience a soft or spongy brake pedal, it could be a sign of a leaking actuator. It's important to address this issue promptly, as it can affect your ability to stop the vehicle safely. Replacing the actuator can be a costly repair, as it requires specialized tools and knowledge. It's best to have this repair done by a qualified mechanic. Regular maintenance of the braking system, such as flushing the brake fluid and inspecting the brake lines and hoses, can help prevent actuator leaks. Keeping the brake fluid clean and free of contaminants will help prolong the life of the seals in the actuator. If you suspect that your GX470 has a leaking actuator, don't delay in getting it checked out. This is a safety-critical issue that needs to be addressed to ensure the proper functioning of your braking system.

Navigation System

Let's talk about the navigation system in the 2006 Lexus GX470. Back in 2006, these systems were pretty advanced for their time, but technology has come a long way since then. One of the biggest issues with the navigation system is that the maps are outdated. Roads change, new businesses open, and old ones close. If you rely on the factory navigation system, you might find yourself driving in circles or missing your destination. Unfortunately, updating the maps on these older systems can be difficult and expensive. Lexus no longer provides updates for the 2006 GX470 navigation system. Another issue is that the navigation system can be slow and clunky to use. The interface isn't as intuitive as modern systems, and it can take a while to input addresses or search for points of interest. The screen resolution is also lower than what you're used to seeing on smartphones or newer car infotainment systems. While the navigation system might not be the most practical feature on a 2006 GX470, it's still a nice-to-have.
